Unable to renew certs on Debian 8 Jessie

I’m trying to renew my cert but run into a problem.

My domain is:

I ran this command:
sudo certbot renew --dry-run

It produced this output:

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you're using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.

Certbot doesn’t know how to automatically configure the web server on this system. However, it can still get a certificate for you. Please run “certbot certonly” to do so. You’ll need to manually configure your web server to use the resulting certificate.

I have created a file in .well-known and it is accessible:

Hi @inferyes

the directory is /.well-known/acme-challenge, not /.well-known.


is redirected to


this is another domain, but the same server, so that may work. It's not a "Connection refused" - error.

Perhaps use the --debug-challenges - option and check, where Certbot creates the file.


Or you should deactivate the redirect to administratix

Aha! I can work with that. Administratix.be is indeed run on the same server, but uses a different folder to serve files.

Thank you.
